The cyclic AMP response element (CRE)-binding protein (CREB) family of activators (CREB1, CREM, ATF1) functions in diverse physiological processes, including the control of cellular metabolism, growth-factor-dependent cell survival, and developement an plasticity of neurons. A diverse range of signals, including cAMP, calcium, stress and mitogenic stimuli, can activate CREB and promote target gene expression. This database is dedicated to catogerize CREB target genes in a comprehensive and easy-to-search way. We have used a multi-layered approach to predict, validate and chracterize CREB target genes. For each gene, we try to provide the following information: 1. CREB binding sites on the promoters, 2. Promoter occupancy by CREB, 3. Gene activation by cAMP in tissues. The data are for humans, rats, and mice. [Information of the supplier, modified]
